방송 영상은 일반적으로 16:9 또는 4:3 화면비로 편집되어 소비되는 반면, 디스플레이 시장에는 다양한 디스플레이 해상도 및 화면비를 가진 모바일 기기가 출시되고 있다. 고해상도 방송 영상을 모바일 단말에서 시청할때, 다양한 화면비의 영상을 재생하기 위해 영상 해상도 및 화면비를 변경하는 과정이 필요하며, 관심 영역 추출기술은 화면비 변경 방법으로 적용될 수 있다. 본 논문은 고해상도 영상을 다양한 화면비와 해상도의 디스플레이 단말에서 시청할 수 있도록 하는 새로운 관심 영역 추출 기법을 소개한다. 제안 방법은 딥러닝 기반 다중 객체 추적기법과 군집화 기법을 적용하여 단일 객체 또는 군중을 중심으로 주요 영역을 포착할 수 있으며, 자연스럽게 변화되는 관심 영역을 출력할 수 있다.
